"When I was a young scientist working on the fledgling creation that came to be known as the internet, the ethos that defined the culture we were building was characterized by words such as ethical, open, trusted, free, shared. None of us knew where our research would lead, but these words and principles were our beacon.
We did not anticipate that the dark side of the internet would emerge with such ferocity. Or that we would feel an urgent need to fix it.
How did we get from there to here?
By suddenly providing the power for anyone to immediately reach millions of people inexpensively and anonymously, we had inadvertently also created the perfect formula for the “dark” side to spread like a virus all over the world. Today more than 50% of email is spam, but far more troubling issues have emerged — including denial of service attacks that can immobilize critical financial institutions and malicious botnets that can cripple essential infrastructure sectors.
Other dangerous players, such as nation-states, started coming onto the scene around 2010, when Stuxnet malware appeared. Organized crime recognized the internet could be used for international money laundering, and extremists found the internet to be a convenient megaphone for their radical views. Artificial intelligence, machine learning, facial recognition, biometrics and other advanced technologies could be used by governments to weaken democratic institutions.
Scientists need to create more advanced methods of encryption to protect individual privacy by preventing perpetrators from using stolen databases. We are working on technologies that would hide the origin and destination of data moving around the network, thereby diminishing the value of captured network traffic. Blockchain, the technology that underpins bitcoin and other digital currencies, also offers the promise of irrefutable, indisputable data ledgers."
